IMPROVEMENT IN ISIIEGHANICALl MOVEMENT.

` "Litige tbztnit rtfemh tu in time etteni ttmt mit making tart nf tige same.

Be it known that I, DANIEL S.`MERRITT, of "-I\Iount Morris, in the county of Genesee, and State of Michigan, have invented a new and useful Improvement in a Method of Increasing Motion; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference markedthereon, and being a part of this specication.

The object of this invention is to so construct a combination of'ilev'ers, cranks, connection-rods, and any proper frame, that themotion may be doubled; or, in other words, that one revolution of the engine will give two reciprocating motions to the pitman. By my arrangement, I contend that, as velocity is power, I am able to increase the power by doubling .the velocity; that one man,'with my apparatus, can do the work of two without it.

In order to accomplish this rcsult,vI construct any suitableframe, A, upon'which I hang a. balance-wheel' and crank, B, to which I-attach a pitman, C, which may be attached directly to the piston-rod of an engine, by any proper joint. I then take four levers, D, of equal length, theirA endspivoted together, so that the levers form equal sides of a square. I attach, by any proper device, one of the corners of said squareto the frame at E, while the opposite corner is pivoted to a proper wrist-pin, F, whic'liworks in the slot G. To this wrist pin is also attachedha pitman, I-I, towhich to attach n. drag-saw, as seen in` the drawings, or any'other device to which it is desired to communicate power. 'llhe'pitman C connects the crank B with the en`ds of'two levers, I, which are pivoted to the end of the pitman C, while the outer ends are pivoted at the other corners of the square,-a t J. K is a brace or arm, attached to the frame, at the outer end of which is placed the guide, L, to

Asustain and hold in position the pitman H.

What I claini'as my inventionand desire to secure by Letters Patent, is The combination and arrangement of the four lev'ers D, the vpitmen C and H, and the levers J, when attached to any suitable frame, A, and constructed andoperating substantially as and for the purposes se't forth. "W,
